X-Perts is a side-scrolling fighting action video game produced by Sega of America and released only in North America for the Sega Genesis in 1996. It is a spin-off of Eternal Champions starring the assassin Shadow Yamoto, who is depicted in her design from Eternal Champions: Challenge from the Dark Side.
The female ninja Shadow leads a group of fellow X-perts in sabotage and other various missions. All three characters have character-specific special moves with differing attributes, along with three unique torture moves, which are used to interrogate various enemies. Players are able to switch characters mid-game in order to carry out different tasks.
The game's plot is based on an alternate timeline in which Shadow Yamoto was not killed by the Black Orchid in 1993. Instead, she formed a vigilante group. In the game, a group of terrorist took over an undersea weapons factory. Unless the United Nations give into their demands, the terrorists will detonate a thermonuclear device that will destroy Earth. Shadow and the X-Perts embark on a mission to avert the crisis.
